I HIDE SETTING-OUT AND OILING MACHINE.

Application filed August a0, 1924. Serial No. 735,080.

This invention. relates to machines having a tool or tools for operating upon pieces of work, and also means for applying a treating material to one or more surfaces of each piece of work either before or after the oper ation of the tool or tools.

The invention is illustrated as embodied in a machine for setting the grain surfaces of hides and other relatively large pieces of leather and for applying oil to the grain surface of each hide or piece of leather immediately following the setting operation. l/Vhile a number of machines have heretofore been proposed for this purpose, none of them has proved satisfactory. Nor have any such machines gone into commercial use so far as applicant is aware. It is still the practice to perform the setting operation upon hides and other pieces of work, utilizing one of the well-known setting machines and then to apply the oil manually with the aicl'of a mop or brush. This'latter operation is slow and laborious and makes necessary repeated handling of each piece of work.

In view of the foregoing, 1t 1s an ob eot of the invention to provide a machine adapted for performing setting operations upon hides .or leather and applying treating material to the grain surfaces of the work in such manner as to secure athorough and uniform application of the material to the work, thus accomplishing the desired results expeditiously and economically in one machine operation. It should be understood, however, that while the invention is herein exemplified as embodied in a machine for setting hides and leather and applying treating material to their grain surfaces, in various aspects the invention is applicable to performing these and similar operations separately as well as in one machine operation.

In accordance with important features of the invention, there is provided means for applying to pieces of work two coats of the treating material in succession, following the operation of a work treating tool, there being a. marked improvement in the results attained through the application of a given amount of treating material dividedbetween successive applications as compared with the results obtained upon applying at one operation the same amount of treating material, since in the former case the. treating material penetrates the work better and with greater uniformity. In the illustrated ma ch ne the desired results are accomplished by providinga work-supporting member for presenting hides or leather to a setting tool and to oil-applying means, the member being operated to move in reverse directions whereby the work is presented twice to the oil-applying means after the operation of the setting tool which is rendered inoperative prior to or during the reverse movement of the work-supporting member.

In another aspect the invention resides in the provision of improved means for applying a treating or coating material to pieces of work wherein a rotary material-applying member is arranged to run continuously in one direction to apply the material to the work while the latter is moved in reverse direction whereby the material is applied more thoroughly and uniformly, particularly to pieces of work having pores or. other surface irregularities, than has heretofore been possible. Conveniently and as illustrated, a brush is employed to apply oil to hides or leather or other pieces of Work and is driven at relatively high speed continuously in one direction during the back and forth movements of the work, the result being that the oil is brushed thoroughly into the work through relative movement of the work and of the brush in the same and in opposite directions. For supplying the brush with the oil there is provided by preference and in the illustrated machine a roll which receives the oil from a reservoir and distributes it upon the brush, an effective driving means for the distributing roll being provided by connections operated in time relation to the work-supportingmember so that I when the latter member comes to rest the distributing roll ceases to supply the oil to the brush. 7

In the illustrated machine the work-sup- Other features of the invention and novel combinations of parts will be described in the detailed specification and pointed out in the appended claims.

Fig. 5 is an enlarged detail plan view of devices at the right hand side of Fig. 1 ;'and

Fig. 6 is an edge view of Fig. 5.

Similar numerals of reference indicate corresponding parts in the several views.

The main frame 1 of the machine is of usual construction and at 2 is a shaft journalcd in the frame and carrying as a hide supporting member a drum or cylinder 3 dis posed horizontally in the frame 1. One side of the member or drum 3 is open or slotted, as indicated at 3 in Fig. 3. T he hide or skin A to be set out or smoothed is hung upon the edge 3 of drum 3, as indicated in Fig. 3. At 4 is a clamp bar for the hides, which extends parallel to edge 3 of the drum and is mounted upon spaced arms 5 journaled upon shaft 2. At 6 are stops carried by the frame 1 at opposite ends of the drum to engage wit-h the arms 5 to limit the movement in one direction of the bar 4, whereby when the parts come to rest there will be a space between the edge 3 of the drum and bar 4 to receive the hide which is subsequently tightly clamped therein. One or more springs 7 are located within the drum, each secured at one end to the drum, at 8, and at its opposite end to bar 4, at 9, which springs serve normally to cause the bar and the edge 3" of the drum to clamp the hide therebetween. At 10 is a setting and smoothing roll carried by shaft 11 journaled in spaced arms 12 (Fig. 4) which are pivoted at 13 in the main frame above the drum 3. The

arms 12 are shown connected by links 14 with atreadle 15 comprising arms 16, shaft 17 and crank arms 18 to which the links 14 are connected at their lower ends. Springs 19 (Figs. 2 and 4) interposed between frame 1 and arms 12 serve normally to hold the hide or portion thereof that is to be operated upon. In the machine illustrated a drive shaft 20 (Figs; 1 and 4) is journaled in suitable bearings in the main frame and is provided with pulley 21 receiving belt 22 from a suitable source of power, said shaft 20 being further provided with pulleys 23, 24 receiving belts 25, 26. The belt 25 passes over a pulley 27 loose on a shaft 28 journal'ed on the main frame, and belt 26 passes over a pulley 29 loose on said shaft. Shaft 28 carries a pinion 30 in mesh with a drive gear 31 secured on shaft 2 of drum 3. Belt 25 passes direct over pulley 27 and belt 26 is crossed so as to drive pulley 29 reversely to pulley 27, for rotating shaft 28 and drum 3 alternately in opposite directions. A clutch member 32 is slidablre on shaft 28 for engagement with pulley 27, and a clutch member 33 on said shaft is also slidable with member 32 for engagement with pulley 29,

and said clutch members are keyed to shaft 28, whereby the latter will be rotated in one has a controlling" arm 37 extending upwardly and adapted to be engaged alternately by clutch shifting members 38, 39, carried by shaft 2 and disposed at an angle to each other, sayat 180. A lever 40 secured to shaft 36 permits manual control of the clutch members. hen the clutch controlling arm 37 is in a central or neutr 1 position neither one of the arms 38, 39 will engage the arm 37, and drum 3 will be at rest. To start the machine the clutch controlling arm 37 is manually shifted so that one of the clutch members or 33 will engage the corresponding pulley to cause rotation of drum 3, and when one of the controlling arms 38 or 39 engages the arm 37 the latter will be rocked to cause uncoupling of one clutch and coupling of the other clutch with the corresponding pulley for reversing the rotation of the drum. The setting roll 10 is rotated by means of pulleys 41 secured on shaft 11 receiving belts 42 from pulleys 43 secured on shaft 20. The parts above described are illustrated as a means of utilizing my improvements for automatically setting and oiling hides in one operation.

A rotative brush 44 (Figs. 3, 5 and 6) is carried by a shaft 45 journaled upon the main frame, the bristles of which brush are so located as to bear on and rotate against the hide A that has been set and smoothed out upon drum 3 preparatory to applying oil or other treat-in liquid to said hide. Shaft 45 of brush 44 maybe rotated in any suitable way at relatively high speed when same direction.

comparedwith the rate of motion of the work supporting drum. I haveshown said'shaft provided with a sprocket wheel 46 (Figs. 2 and 4) receiving achain47 from a sprocket 48 secured on shaft 20, whereby the brush may be rotated continuously in one direction with shaft '20. Hence the brush applies oil or other treating liquidto the hide in two coats, one while the drum is rotating away from the front of the machine and again upon reverse movement ofthe drum inreturning to initial position, v This arrange ment results rubbing the oil or other treating liquid into the hid'e'in avery'athorough manner since by applying the treating liquid first in one direction and then in another the liquid is introducedmore effectively into the pores and hair foll'icles of the hides than it would be by relative move ment of the brush and workin one direction only. At 49 (Figs. 3 and 6) is a distributing roll shown carried by shaft 50 journaled in hearings on the main frame, said rollbeing in position to be engaged bythe brush 44 to distribute the treating. liquid to tt The distributing roll 49 may be u i tile 12love:

fluted or serrated on its surface and shown operative in a tank or bath 51 supported on the main frame, (Fig. The oil-distributing'roll 49 is preferably rotatedcontin'uously in one direetion'and may be driven by any suitable means. I have illustrated ratchet wheels 52', 53 (Figs. 4' and 6) secured upon shaft 50, said ratchet-wheels have their teeth disposed in the same direction to be engaged by spring-pressed pawls 54, having their operating ends pointing in the Pawl54 is pivotally carried by gear 57 journaled upon shaft 50, and

pawl 55 is pivotally carried by a gear 56' journal'cd on shaft 50. As shown gear 57' is in mesh with pinion 58'journaled at 59 and attachedto and operated by gear 60 in mesh with gear 31. Conveniently gear 56" is driven directly from gear 31. \Vhen gear 31 rotates in one direction with the drum 3 the pawl 55 will rotate shaft 50 and the oil distributing roll 49 in one direction, and when the gear 31 and drum 3 rotate in thereverse direction the other pawl 54 will rotate shaft 50 and oil distributing roll 49 in the same di-' rection', as betoreso that said roll will be rotated always in one direction. Moreover, when the drum is stationary the fluted'roll 49 is also stationary so that oil is not lifted from the tank 51 and wasted while no work is being done. Theratio of gearing shown for rotating oil distributing roll 49 may be varied for any desired speed of rotation of said roll. 1

A flexible shield or apron 61 (Fig; 3), of suitable material impervious to oil and other liquids, is shown disposed in the ri between the edge 3 of the drum 3 and the hide-clamping bar 4, to which the drum from drippings.

corresponding edges of'the shield or apron 61 are secured in any suitable manner. The shield or apron 61 is suflioiently' flexible .to enable bar 4" to move to open position, and subsequently to closed position to engage the hide resting upon the edge .3 of erum 3. The shield or apron willcatch the drip A shield 51 is shown depending below tank 51 to protect the outer surface of the Since the portion of each hide exposed for treatment on the surface of the drum is dif- 1 p 1 o I 161611;) 111 SJZG and H1 5118.138 1X1 etlCl'l SllCCGQEling operation, it follows that the area of the uncovered portions being of considerable extent where the pieces of work are smaller than usual. Hence, during operations of the machine, the blades of the roll '10 in contacting with the uncovered surface of the drum wet with oil or other treating liquid will pick up in time a considerable amount of treating liquid. Even if the pieces of work, that is, the hides, he of a selected lot of substantially that of every other, thus leaving uncovered portions of the drum surface of 1rregular and variable area; Hence, oil or other treat.-

To prevent spattering of oil or other treatin li uid r. 3011 the work and u on the operator, from the. roll-1O a shield 62 is suit-ablysupported upon the main frame and arranged to extend over and in front of the setting roll 10. The lower portion of the shield'62 adjacent to bar 4, (Fig. 3), is provided with a channel or gutter 63,10- cated along the inner lower edge of the shield to catch oil drippings from within the shield. Any suitable outlet tube may lead from the gutter 63 to a receptacle for the drippings.

As the drum rotates in the direction of the arrow in Fig. 3 the'edge 8" will force the adjacent part of the hide against bar 4-, whereby the hide will be clamped by the tension of springs 7. Continued rotation in said direction of drum 3 carries the outer portion of the hide on the drum in contact with the setting roll 10, the operator operating the pedal 15 downwardly at the appropriate time, against the tension of. the supporting springs 19 2 and l), to bring the roll 10 into contact with the hide. As the hide travels with the drum beneath roll 10 the rotation of the latter causes set ting and smoothing of the hide in an extended condition on the outside of the drum and then the drum carries the hide forwardly into engagement with brush 4%, which will rotate in contact with the hide and apply oil thereto. hen the oil has been applied upon the hide the drum 3 will reverse its direction of rotation, by means of the operation of the clutch devices hereinbefore described, and the operator will release the treadle so that roll 10 will be lifted from the hide by the springs 19 2) in order that the outer or oiled portion of the hide may be left in its oiled and set condition and not have any portion of the oil removed by the bladed cylinder nor the surface of the hide operated upon by a cylinder moving in the wrong direction relatively ,to the work. During this reverse movement of the drum, the brush i l applies the second coat of oil and rubs it in thoroughly during the reverse relative movement of the drum and brush. As usual in this class of machines, the hide will be removed from the drum and reversed as many times as required to present its several surfaces on the exterior of the drum to be set and oiled each time that the drum rotates back and forth to carry the set and smoothed. hide in contact with. the oiling brush. Any time that the surface of the exposed portion of the hide has been oiled during rotation of the drum from front to rear, the drum may be reversed by the operator by shifting the member 37 whereupon the drum returns to initial position for shifting ofthe hides or applying new hides.

In accordance wit my invention I am en abled with one placing of a hide in the machine to set and oil its exposed surface while it is upon the drum, and the oiling will be effected in a smooth and uniform manner with a great degree of accuracy and with a minimum loss of oil whereby the operation of setting and oiling hides and skins is expedited and the cost reduced with resultant uniformity of production.
